Exceptional audio performance
The drivers of the HE400i headphones benefit from a massive and ultra-light diaphragm offering an excellent time response with a rigorously controlled tonal balance. They can withstand strong input signals.
The headphones have a sensitivity of 93dB for an impedance of 35Ω, which allows operation both with a modest source (smartphone) as well as with headphone amplifiers capable of developing significant power.
Superb design
The HE400i is above all a headphone with an impeccable design that measures itself against the market leaders. Its shells are in ABS polymer with a very modern glossy black finish.
The earpads are made of synthetic leather with velor pads, ensuring both comfort and optimal support while helping to isolate external noise. The contact points with the head are specially arranged to limit wear fatigue.
